University of Rochester junior Nolan Sparks helped the Yellowjackets upset No. 6 Marietta in their second game of the D3 Baseball Showcase, allowing just one unearned run on four hits, walking three and striking out seven over 5.0 innings pitched against the Pioneers, earning the win in his first start of the year. After Sparks worked out a of bases-loaded jam in the top of the first, allowing just one, unearned run, the junior allowed just three hits the rest of his outing, working 1-2-3 frames in the third and fourth after Rochester extended it’s lead, and stranding a pair of baserunners in the second and fifth.
